Entertainment
If walking down the street and going to the local supermarket isn’t entertaining enough, consider the following:
Spectator Sports
Going to watch Sumō is an absolute highlight so you may want to check the dates of the six 15-day tournaments and plan your trip to Japan from there. Sort out tickets online.
Heading to a baseball game in Japan is also an amazing experience, with the fervent crowd providing half the entertainment.
Theatres
See Traditional Theatre for information on going to watch the performing arts of Kabuki, Noh and Bunraku.
Movies
Movie theatres (cinemas) are in all cities and are an interesting experience - make sure you’re going to a movie in a language you can understand! - or if not, that it’s sub-titled.
Concerts
Japan is a popular place to play for all sorts of international acts. Check out who is coming and get tickets at Japan Concert Tickets.
